Be i known that I, MARcUs 'AnnATAs Kossurn SHOTWELL, a citizen of the United' States, residingat 'Miamifin the, county of Dade andState ofFlorida, have invented a new and useful Automobile-Tire, of which" the following is a'specification.

'My inventlon relates to improved automo j biletires, wherein no rubb.er,*"pneumatic tubes, or air cushions "form a part; of their 1 construction, the object bein'g to provide tires at" less cost and of more'enduringchar-L acter, thus obviating the expense and annoy? ance of punctures andblowouts.

I attam these objects by the mechanismi accompanying drawings,

illustrated in the in .which n 4 y Figure 1, is aside. elevation, illustrative of -my 'tire,*in its respective position,'attached to the wheel, a section of its interior exposed to view.

of its" formation.

throughout the several views.

As disclosed in the accompanying draw-- ings, A denotes the felly of a wheel body which has disposed circumferentially there- 1 and of a width'less than the widthof'the felly A, said ring bepositioned substantially centrally. of the e y.

The ring 1 is substantially U-shaped in cross section and extending within and supported by the'ring 1 is a plurality of transversely arranged springs 2. Each of the springs 2 is formed from a single strip of material, preferably steel, which is bent to form a straight portion a, outwardly extending side portions 1) at right angles to the base portion, and. then continued to form substantially a circle, the extremities of the strip lapping each other at the tread portion of the tire. The base portion a and the side fiaortions b of each of the springs 2 snugly t within the ring 1 or more particularly the channel as afforded by the side flanges Inclosing the springs 2 is a sectional flexible casing 3 and disposed over the casing 3 is an auxiliary sectional casing l. The marginal portions of the casings 3 and 4, when applled, overlie the outer faces of the flanges 1 and coacting with said overlying portions are the clamping. rings 7. Disposed through registering perforations 10 in s .2, a ,CIQSS' sect a iew, illu r ive the "side fiangesl the marginal portions {of the casmgs 3' and 4, and the rings 7, area plural ty of circumferenti-ally spaced bolts 8 and with which coact the nuts 9, whereby the several parts are effectively maintained in proper assemblage.

Disposed throughout the? substantially ciri cular portion} ofthe springs 2 is ametallic'J i pdrtionsof the springs "2 Pandthe inner pei tubular core 5 which contacts with such riphery of the core" 5"issplit' circumferen tially' forming slightly spaced edges which bear uponja strip of cushioning material 6. The strip 6 is also dis tially' of the felly j A an tween the sidefportions bof the springs and rests upon the base portions athereof. The core 5. acts ingconjunction with the springsv 2'to supportthe load imposed-{upon the wheel body.

osed circumferen-j is pos tioned be- From the foregoing "description, it is thought to be obvious that an automobile tire constructed in accordance with myinvention" 'is particularly well adapted foruse by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish-to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice ex cept as hereinafter claimed.

I claim:

1. A tire of the class described comprising a member adapted to be disposed circumferentially around a wheel body, said member being substantially U-shaped in cross section, a plurality of transversely disposed springs, each of said springs having a base portion contacting with the member and having outwardly extending side portions in contact with the sides of the member and continued to form substantially portions in contact with. the sides of .the-' member and continued to form substantially a circle, the extremities of thespring lapping each other at the tread portion of the tii'e,a' casingdisposed over the springs and secured to the sides of the member, and

stantially circularportions of the vsprings, said co-re being circumferenti-ally split.
